Title (EN) METHOD OF TREATING RAZOR BLADE CUTTING EDGES
(FR) PROCEDE DE TRAITEMENT DES BORDS TRANCHANTS D'UNE LAME DE RASOIR
Abstract: front page image
(EN)The present invention relates to an improved method of forming a polyfluorocarbon coating on a razor blade cutting edge comprising the steps of subjecting a fluorocarbon polymer having a molecular weight of at least about 1 000 000 to ionizing radiation to reduce the average molecular weight to from about 700 to about 700 000; dispersing the irradiated fluorocarbon polymer in an aqueous solution; coating said razor blade cutting edge with the dispersion; and heating the coating obtained to melt, partially melt or sinter the fluorocarbon polymer.
(FR)L'invention concerne un procédé amélioré de formation d'un revêtement en polyfluorocarbone sur le bord tranchant d'une lame de rasoir, ce procédé consistant à soumettre le polymère de fluorocarbone ayant un poids moléculaire d'au moins 1 000 000 envrion à un rayonnement ionisant afin de réduire le poids moléculaire moyen d'environ 700 000, à disperser le polymère de fluorocarbone irradié dans une solution aqueuse, à revêtir le bord tranchant de la lame de rasoir avec la dispersion, et à chauffer le revêtement obtenu afin de fondre partiellement ou fritter le polymère de fluorocarbone.
